Constant fears of foodborn illnesses.

I always have a fear that every food I eat could have a foodborn illness such as: Salmonella, Cholera, and Norovirus. It makes me always cautious when I eat food and makes me extremely anxious when I feel a small change in my body. I have to constantly Google “Food Recalls” to make sure I will be fine. But I also get changes in my body due to anxiety such as: Chills, loss of appetite, constipation, and dry throat and mouth. Does anyone have any help or advice to stop this problem?
